we develop very well through those years even the external environment is not conducive to the whole steel industry. With the prosperity of our group, our company always bear its staff who contributes to its growth in mind, and always on the way to improve welfare and treatment. That makes us staff and work with pleasure. On the other way, they creat a better and stronger our group. That may be one of the key factors why we develop so rapidly those years. Here we can say proudly “we are family”.
40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. steel A573 Grade 58, 40Cr alloy chemical composition (C: 0.37 ~ 0.44, Si: 0.17 ~ 0.37, Mn: 0.50 ~ 0.80, Cr: 0.80 ~ 1.10, Ni: ≤0.30, P: ≤0.030, S: ≤0.030, Cu: ≤0.30, Mo: ≤0.10). Heat treatment: First quenching heating temperature (℃): 850; coolant: oil; Temperature heating temperature (℃): 520. 40Cr steel tensile strength (σb / MPa): ≥980. Yield point (σs / MPa): ≥785
Under the action of the roller and the plug, a cavity is formed in the blank, which is called the blank. Then send it to the automatic tube rolling machine to continue rolling. Finally, the wall thickness of the whole machine is equalized and the diameter is calibrated by the sizing machine to meet the specification requirements. It is an advanced method to produce steel A573 Grade 58, hot-rolled seamless steel tube by continuous rolling mill.
According to the data released by the world iron and Steel Association, the world pig iron production in March 2020 was 103 million tons, a year-on-year decrease of 3.5%, a year-on-year increase of 1.8% in February, and the overseas pig iron steel A573 Grade 58 production excluding China was 36.309 million tons, a year-on-year decrease of 11%. In March, except for China and Russia, pig iron production increased by 1%6, other countries' pig iron steel A573 Grade 58 production decreased year-on-year, with 28 EU countries reducing by 14.2%, 3 CIS countries (Russia, Ukraine and Kazakhstan) reducing by 0.8%, India reducing by 14.6%, Japan reducing by 7.9% and South Korea reducing by 9.5%.

Recently, the steel A573 Grade 58 price has fallen into a dilemma, and Tangshan production restriction has started again. When the market transaction is weak, the steel A573 Grade 58 price gain support again. Although the high demand is not good at present, which will restrain the rise of steel A573 Grade 58 price, the preference of market mentality and cost side make most steel A573 Grade 58 manufacturers optimistic about the prosperous season. Therefore, it is expected that the steel A573 Grade 58 price will be easy to rise and difficult to fall in the near future, so it is suggested that businesses can make up stocks at low prices.
